Lines 1-11 are written to the right of the plan lines 11-13 underneath it.  J. P. R.]

III.  Castles and Villas.

A. Castles.

Pl.  LXXX, No. 1 (P.  V. fol. 39b; No. d’ordre 2282).  The fortified place here represented is said by Vallardi to be the_ “castello” at Milan, but without any satisfactory reason.  The high tower behind the “rivellino” ravelin—­seems to be intended as a watch-tower.

Pl.  LXXX, No. 2 (MS. B, 23b).  A similarly constructed tower probably intended for the same use.

Pl.  LXXX, No. 3 (MS. B).  Sketches for corner towers with steps for a citadel.

Pl.  LXXX, No. 4 (W.  XVI).  A cupola crowning a corner tower; an interesting example of decorative fortification.  In this reproduction of the original pen and ink drawing it appears reversed.

B. Projects for Palaces.

Pl.  LXXXI, No. 2 (MS. C. A, 75b; 221a, see No. 748).  Project for a royal residence at Amboise in France.

Pl.  LXXXII, No. 1 (C.  A 308a; 939a).  A plan for a somewhat extensive residence, and various details; but there is no text to elucidate it; in courts are written the three names: 

Sam cosi giova
       (St. Mark) (Cosmo) (John),
arch mo nino

C. Plans for small castles or Villas.

The three following sketches greatly resemble each other.  Pl. 
LXXXII, No. 2 (MS. K3 36b; see No. 749)._

Pl.  LXXXII, No. 3 (MS. B 60a; See No. 750).

Pl.  LXXXIII (W.  XVII).  The text on this sheet refers to Cyprus (see Topographical Notes No. 1103), but seems to have no direct connection with the sketches inserted between.

Pl.  LXXXVIII, Nos. 6 and 7 (MS. B, 12a; see No. 751).  A section of a circular pavilion with the plan of a similar building by the side of it.  These two drawings have a special historical interest because the text written below mentions the Duke and Duchess of Milan.

The sketch of a villa on a terrace at the end of a garden occurs in C. A. 150; and in C. A. 77b; 225b is another sketch of a villa somewhat resembling the_ Belvedere of Pope Innocent VIII, at Rome.  In C. A. 62b; 193b there is a Loggia.

Pl.  LXXXII, No. 4 (C.  A. 387a; 1198a) is a tower-shaped_ Loggia above a fountain.  The machinery is very ingeniously screened from view.

748.

The Palace of the prince must have a piazza in front of it.

Houses intended for dancing or any kind of jumping or any other movements with a multitude of people, must be on the ground- floor; for I have already witnessed the destruction of some, causing death to many persons, and above all let every wall, be it ever so thin, rest on the ground or on arches with a good foundation.
